The object of this invention is to facilitate the removal of bricks fromthe molds of brickmachincs.

The invention consists in a brick-machine constructed with a slidingframe having crossbars and carrying molds open at the corners, andprovided with lugs and pins, with which engage double hooks attached toshafts carrying cam-plates and connected with sliding bars operated byarms attached to a crank- W'ith the frame carrying the molds areconnected bars extending upon the opposite sides of the headblock, andprovided with cleats engaging with legs attached to the guard-plate andstrengthened in place by side boards, to one of which is pivoted a leverconnected by a bar with one of the said extended bars, the said sideboards and extended bars being connected byaspring, so that themold-carryin g frame can be readily raised and lowered, and will carrythe said guard-board with it in its outward and inward movement. Thebars attached to the moldcarrying frame are connected with the sideboards of the guard-plate by bars pivoted to the rigid arms of arock-shaft to cause the said bars to move up anddown together. To theside boards connected with the guardplatcis journaled ashaft carryingwater-tanks and provided wit-h a crank-arm, whereby the head-block canbe readily wet to prevent the clay from adhering thereto, as will behereinafter fully described.

A represents the base platform of a brickmachine. formed'openings B,through which the clay is forced into the molds 0 from the body D of thepress by the mechanism described in my specification for brick-machines,for which a patent was allowed July 1, 1884, or other suitablemechanism.

The ends of the sides and ends of the molds O are mitered to each other,and to the outer sides of the said ends are attached, or upon them areformed, lugs E, the lugs at each corner projecting parallel with themiters at the said corner. I

To the lugs E at each corner are attached pins F, which project aboveand below the said lugs, and with which engage the double hooks G,placed above and below the said lugs and attached to a rod, H. The rod Hpasses down between the lugs E of each pair, and to it is attached across-plate, I, which, when the said rod is turned to unhook the hooksG, acts as a lever or double cam to force the said lugs apart. The rodsH rock in bearings in bars J, placed at the outer and inner ends of themolds O, and attached at their ends to the side bars of the frame K,which incloses the said molds O. The upper parts of the rods H are bentoutward and then downward, and their ends are journaled in hearings inbars L, placed at the ends of the molds O and In the top of the platformA are sliding in keepers M, attached to. the inner ing bars L areconnected the upper ends of arms N, the lower ends of which are formedupon or rigidly attached to a shaft, 0, rock-' ing in bearings in theouter and inner crossbars of the frame K. The shaft 0 passes through thespace between the molds 0, and

its outer end projects and has a crank, P, at-' .tached to it forconvenience in turning the said shaft to operate the sliding bars L.

To the outer cross-bar of the frame K is attached a coiled spring, Q, orother suitable spring, the free end of which rests against the crank Pto hold the sliding bars L pushed forward, and the hooks G in gear withthe pins F. The ends of the rear crossbar of the frame K project, and tothe said projecting ends are rigidly attached the for ward ends of twobars, R, which extend inward along the opposite sides of the head-blocksS, placed at such a distance below the platform A as to receive theframe K and the molds O, and serve as a bottom to the said molds whilebeing filled with clay.

To the bars R are attached beveled cleats T, which slide up and downalong the undercut beveled sides of the legs U, attached to the cornersof the guard-plate V, and which are made of such a length as to supportthe said guard-plate V close against the lower side of the platform Aagainst the downward pressure of the clay, and thus prevent any clayfrom being forced through the openings B in the said platform when theframe K and the molds U are drawn forward to discharge the moldedbricks. The cleats T and legs U cause the guard-board V to be movedforward and back by and with the frame K, and the said legs arestrengthened in position by side boards, W, attached to them and to thesaid guard-plate V.

To the board W, near its rear end, is pivoted the end of a lever, X,which extends forward to or nearly to the forward corner of the frame K,and to which is attached the upper end of a connecting-bar, Y. The lowerend of the bar Y is pivoted to the bar R midway between the guide-cleatsT, so that by pushing downward upon the free end of the said lever X,when the frame and filled molds have been drawn forward, the bars R,frame K, and molds G will be lowered, and by operating the crank P themolds will be opened and the bricks discharged upon the offbearing boardZ, placed upon suitable supports or held at the forward end of thehead-block.

To the middle part of the bars R are pivoted the lower ends of the shortbars a, the upper ends of which are pivoted to the forwardly--projecting ends of crank-arms b, rigidly attached to the ends of ashaft, c.- The shaft 0 is journaled to the rear parts of the boards W.The bars a, arms b, and rock-shaft 0 cause the two bars R and themold-carrying frame K to move up and down squarely.

d are water-tanks placed beneath the forward part of the guard-plate Vand attached to a shaft, 6, which rocks in bearings in the forward partsof the boards W.

To one end of the rock-shaft e is attached or upon it is formed acrank-arm, f, which projects forward to or nearly to the forward cornerof the frame K, so that it can be readily operated when the said frame Kand its attachments are drawn forward to rock the shaft 6 and tilt thetanks d to wet the face of the head-block S, to prevent the clay whenforced into the molds 0 from adhering to the said head-block.

The side boards W are strengthened in positionby cross-bars g h, to therear one, h, of which is attached an arm, '5, with which is connectedthe mechanism for moving the frame K and molds 0 out and in, as fullyshown and described in my application for a patent allowed July 1, 1884,previously referred to.

The bars R, frame K, and molds G are raised after the bricks have beendischarged by the spring j, one end of which is connected with theguard-plate V or side board WV, and its other end is connected with thebar R.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a brick -machine, the combination, with thesliding frame K, having cross-bars J, of the molds 0, open at thecorners and provided with lugs E and pins F, the double hooks G, thecam-plate I, the bent rod H, and the sliding bars L, and armedcrank-shaft O, and the spring Q, substantially as herein shown anddescribed, whereby the said molds can be opened and closed by operatingthe said armed crank-shaft, as set forth.

2. In a brick-machine, the combination, with the platform A, havingopenings B, the guard-plate V, the head-block S, and the frame K,carrying the molds O, of the bars R, having cleats T, the legs U, theside boards W, the lever X, and the connecting-bar Y, and spring j,substantially as herein shown and described, whereby the mold-carryingframe can be raised and lowered and will carry the said guard-board withit in its outward and inward movements, as set forth.

3. In a brick machine, the combination, with the bars R, attached to themold-carrying frame K and the side boards W, of the rock shaft 0, havingrigid arms b, and the connecting-bars a, substantially as herein shownand described, whereby the two bars R are made to move up and downtogether, as set forth.

4. In a brick-machine, the combination, with the head-block S, and theside boards WV, connected with the guard-plate V, of the water-tanks (Z,the shaft 6, and its crank-arm f, substantially as herein shown anddescribed, whereby the said head-block can be readily wet to prevent theclay from adhering thereto, as set forth. I

5 In a brick machine, the combination, with a sliding frame and moldscarried in said frame, of cranked shafts, devices connected with saidcranked shafts and the molds, for locking together and separating saidmolds at their corners, and of devices for operating the said crankedshafts, substantially as herein shown and described, whereby the brickswill be discharged from the molds, as set forth.
